Product Decision Trees

The following product decision trees were created by Purdue University to identify the potential outcomes and safety of select HBV products.

Cream Pies

Cream Pies Decision Tree flowchart from Purdue University. Decision points: pH of pie filling less than 4.6 (Yes -> safe, No -> next check), water activity more than 0.95 (Yes -> not safe, No -> next check), water activity less than 0.92 (Yes -> safe, No -> next check), pH less than 5.96 AND water activity between 0.92 and 0.95 (Yes -> safe, No -> not safe).

Cheese Bread
